A familiar Leeds United failing came to the fore again on Saturday afternoon, when a first-half set-piece goal was enough to give Charlton a 1-0 victory over Marcelo Bielsa's side at The Valley.
Macauley Bonne was in the right place at the right time, after Kiko Casilla parried Tom Lockyer's volley from a corner onto the back of Bonne, with the ball then finding the back of the net.
The 1-0 defeat has seen Leeds drop out of the top two and although the Whites can boast of the best defensive record in the league, crucial goals from set-pieces are mounting up.
Leeds now sit fourth in the table and welcome new leaders West Brom to Elland Road on Tuesday night, with Bielsa acknowleging that set-pieces are an issue for his team.
"There is a fact," the Whites head coach said following the 1-0 reverse at The Valley. "We are receiving goals. When you receive goals from set-pieces, you can explain in two ways.
"When you lose the one v one in the box or when the opponent flicks the ball on and the opponent gets the second ball. The goals this season have more relationship with the flick on rather than the one v one. This is a situation that is very difficult to manage.
"We cannot say our team loses its concentration and also we cannot say we let the opponent free in the box. Or we cannot say we are not adapting to set-pieces the opponent prepares. The reality is that became the only resource of our opponent ."
The Baggies head to West Yorkshire having scored the joint-most number of goals in the league, bagging 17 times in their nine matches so far.
